CO2 as a Redox Shuttle Enables Photocatalytic Dehydrogenative Decarbonylation of Biomass‐Derived Alcohols to Light Alkanes

open access: yesAngewandte Chemie, EarlyView.
A heterogeneous photocatalytic system has been developed that enables the dehydrogenative decarbonylation of primary alcohols under visible light using highly dispersed oxidic iron sites supported on aryl‐modified graphitic carbon nitride (Fe@f–gC3N4).

A rational approximation to the evolution of a free surface during fluid withdrawal through a point sink [PDF]

open access: yes, 2010
The time varying flow in which fluid is withdrawn from a reservoir through a point sink of variable strength beneath a free surface is considered. Asymptotic techniques are used to derive an approximate solution to the flow that is valid at intermediate ...

Magnesium‐Retention Assisted Synthesis of High‐Performance Zintl Thermoelectrics

open access: yesAngewandte Chemie, EarlyView.
Mg volatilization and chemical instability during high‐temperature synthesis hinder the scalable fabrication of Mg‐based thermoelectrics. Here, a magnesium‐retention assisted synthesis (MRAS) strategy stabilizes Mg using a sacrificial Mg reservoir and an inert‐gas‐regulated melting environment.

Direct and Indirect Effects of Large-Scale Forest Restoration on Water Yield in China’s Large River Basins

open access: yesRemote Sensing
Emerging evidence indicates that large-scale forest restoration exhibits dual hydrological effects: direct reduction of local water availability through elevated evapotranspiration (ET) and indirect augmentation of water resources via enhanced ...

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Impact of rapid urbanization on groundwater storage variation amid climate change in the Yangtze River Basin

open access: yesJournal of Hydrology: Regional Studies
Study region: The Yangtze River Basin (YRB), China. Study focus: The escalating dependence on groundwater resources under climate change pressures is potentially exacerbated by urban expansion, which may amplify groundwater depletion risks.
